Gallstones 1.3 cm are not serious if there are no other symptoms, but are serious if accompanied by biliary colic, jaundice and other symptoms. Gallstones ≥2 to 3 cm are indications for surgical removal of the gallbladder, and gallstones 1.3 cm have not yet been reached, i.e., they are not serious if they are not accompanied by clinical symptoms such as jaundice. Gallbladder stones <2~3cm without clinical symptoms are not serious and only require clinical observation. However, gallbladder stones with symptoms or complications are serious and cholecystectomy is the preferred treatment. When the number of gallstones is large and the diameter of the stones is ≥2~3cm, it is easy to cause bile duct blockage, which has reached the indication of surgery, and it is also a more serious case, so surgery should be considered. Gallstones should pay attention to control cholesterol intake, to maintain a reasonable weight and lifestyle. Once there is any discomfort, you should seek medical treatment in a reasonable and timely manner to avoid delaying your condition.
